Solutions

1. A non-standard function call was used while strict JPA compliance was requested. Rewrite the call using JPA-standard FUNCTION('name', ...) syntax or disable strict JPA compliance.

When it happens

Trigger: An HQL-specific construct is used while strict JPQL compliance is enabled: Strict JPA query language compliance was violated: improper non-standard function call

Common situations: Applications running with hibernate.jpa.compliance.query=true (or JPA-compliance mode) that submit queries using Hibernate extensions such as collations, tuples/row value constructors, HQL collection functions (maxelement/elements/indices), value()/key() on non-Map types, or non-standard function calls without FUNCTION() syntax.
